The arcuate projection 2001 is offset from the axial direction of the scrub roller 1 and may alternatively be tapered in an arcuate manner in or against the direction of rotation of the scrub roller 1.

As shown in fig. 3, 4, 5 and 6, the water diversion structure 21 includes a water diversion portion 211 contacting the surface of the scrubbing roller 1, a water storage portion 214 connected to the water diversion portion, a guide bar 212 for interfering the two end surfaces of the scrubbing roller 1, and an extension portion 210 having a first gap B1 between the surface of the scrubbing roller 1, the circumferential end of the water diversion portion 211 is provided with a second interference portion 2111 forming a water-tight contact with the surface of the scrubbing roller 1, and the two ends of the length direction of the water diversion portion 211 are respectively provided with a guide bar 212 for interfering the two end surfaces of the scrubbing roller 1, that is, the guide bar 212 is in partial contact with the surface of the scrubbing roller 1.

As shown in fig. 2 and 3, the cleaning mechanism 2 further includes a first fixing member 22 and a second fixing member 23 that cooperate with the sealing portion 202 to fix the water diversion structure 21, where the first fixing member 22 needs to be fixed by the second fixing member 23, one side surface of the first fixing member 22, which is close to the scrubbing roller 1, is provided with an arc structure, and a second gap B2 that is communicated with the first gap B1 is provided between the arc structure and the surface of the scrubbing roller 1, and the first gap B1 and the second gap B2 form a pressure release chamber B, and because the first gap B1 and the second gap B2 form a larger area projection on the surface of the scrubbing roller 1, when pressure needs to be released, the pressure release air outlet 27 and the pressure release chamber B are communicated by means of an electromagnetic valve (not labeled in the drawing), so that the pressure can be absorbed by the scrubbing roller 1 faster, and thus, phenomena such as bubbles are avoided when the pressure is released to the scrubbing roller 1.

As a further improved embodiment, as shown in fig. 11, the first fixing member 22 is of a unitary structure, so that the internal structure of the cleaning mechanism 2 can be further simplified, and the processing and manufacturing difficulty of the cleaning mechanism can be reduced.

As a further improved embodiment, as shown in fig. 2 and 4, the pressure release air outlet 27 is directly communicated with the pressure release chamber B, so that the internal structure of the cleaning mechanism 2 can be further simplified, and the processing and manufacturing difficulty of the cleaning mechanism can be reduced.

When the third interference part 231 is positioned on the second fixing member 23, it can be conveniently detached, thereby facilitating cleaning.

As a further improved embodiment, the third interference part 231 may be provided on other components, if necessary, and may be easily removed, thereby facilitating cleaning.

The surface area of the scrubbing roller 1 forming a part of the pressure release cavity B is larger than that of the scrubbing roller 1 forming a part of the sealed liquid exchange area A, and the pressure release can be easily carried out due to the fact that the surface area of the scrubbing roller 1 is smaller and the generated air is limited, and the part of the pressure release cavity B is larger.

As shown in fig. 2 and 3, the water diversion portion 211 extends to point to the inside of the sealed liquid exchange area a, a portion of the water diversion portion close to the sealed liquid exchange area a contacts the surface 1 of the scrubbing roller, and a gap B1 is provided between a portion of the water diversion portion far from the sealed liquid exchange area a and the surface 1 of the scrubbing roller.

The guiding portion of the pressure relief opening 222 can increase the air outlet area of the pressure relief opening 222, further reduce the air outlet flow rate, and simultaneously, the discharged air can be more favorably dispersed on the surface of the scrubbing roller 1 uniformly, so that the noise generated in the pressure relief and air exhaust process of the scrubbing device is further reduced.

As a further improved embodiment, as shown in fig. 8, an exhaust pipe interface seat 35 for connecting a pressure relief pipeline (not labeled in the drawing) is arranged in the middle of one side of the first fixing piece 22 facing away from the scrubbing roller 1 according to needs, an air outlet 27 is arranged in the exhaust pipe interface seat, when the pressure accumulated in the scrubbing device needs to be relieved, the pressure relief pipeline is connected to discharge air to a pressure relief cavity B through the air outlet 27 in the exhaust pipe interface seat 35, and the pressure relief cavity B further leaks the accumulated pressure, so that the pressure relief of the accumulated pressure in the scrubbing device is realized.

As a further improved implementation manner, in the above embodiment, the cross section of the first interference portion 200 may be triangular, and the top of the triangle is of a smooth arc structure, so that the resistance generated by the contact surface during interference can be reduced, and meanwhile, the friction loss to the scrub roller 1 can be reduced, and the service life is prolonged.

As a further improved embodiment, as shown in fig. 7 and 9, the second fixing member 23 continues to extend in the longitudinal direction at both ends of the third interference portion 231 and simultaneously extends radially upwards along the outer surface of the scrubbing roller 1 to form a water pocket protrusion 234 in a shape of a letter a, and the second fixing member 23 continues to extend at both ends at the water pocket protrusion 234 while the interference with the outer surface of the scrubbing roller 1 gradually decreases to zero until a gap is left between the two to form a collapse section 232.
